ＣＳ_２在Ｃｕ－Ｓ键中插入产物（Ｐｈ_３Ｐ）_２Ｃｕ（Ｓ_２ＣＳＰｈ）与ＣＨ_２Ｃｌ_２－Ｃ_２Ｈ_５ＯＨ混合溶剂反应，获得单核铜配合物（Ｐｈ_３Ｐ）_２Ｃｕ（Ｓ_２ＣＯＯＣ_２Ｈ_５）和双核铜配合物（Ｐｈ_３Ｐ）_３Ｃｕ_２Ｃｌ_２等化合物晶体，用Ｘ－射线单晶衍射法测定前者的晶体结构。晶体的化学式为Ｃ_（３９）Ｈ_（３５）ＣｕＯＰ_２Ｓ_２，分子量为７０９．３，空间群Ｐ２１／ｎ，ａ＝９．３２９（６），ｂ＝１８．６６４（１１），ｃ＝２０，３４１（１３），β＝９５．５９（５）°，Ｖ＝３５２５（４）~３，Ｄ_ｃ＝１．３３７ｇ／ｃｍ~３，Ｚ＝４，Ｆ（０００）＝１４９２，μ＝０．８５２ｍｍ^（－１），Ｒ＝０．０４５。
Mononuclear copper complexes with structure of (Ph_3P)_2Cu (S_2CSR) formed by insertion of CS_2 into Cu-S bonds can react with various solvents undergoing some nucleophilic reactions.The title compound was obtained from the reaction of starting material (Ph_3P)_2 Cu (S_2CSPh)with CH_2Cl_2-C_2H_5OH mixed solvent and then self-assembly in the solution.The crystal belongs to the space group P2_1/n ,a= 9. 329(6),b= 18.664(11),c= 20.341 (13)A,β= 95. 59(5)°,V =3525(4) A 3.D_c =1. 337 g/cm￣3.Z= 4. The final R is 0. 045 for 3150 independent reflecrions.The complex contains a dithiocarbonate ligand.
